| theShirbiny | Hello everyone \o/ | 14:01 |
|---|---|---|
| elacheche | Helloo! :) | 14:35 |
| elacheche | theShirbiny: This seems a dump question, but I like getting real feedbacks on my "critical" questions instead of reading tutos.. I'm running out of space on some production VMs.. I thought that I can use NFS or SSHFS to mount a remote disk and migrate my data in there.. Do you have recommendations? Is there any clustering tips (so when a remote disk isn't rechable I can still have my data r/w) | 18:10 |
| elacheche | I know, dump and not well formated question, but It's just something that I was thinking about and thought I should ask before living the office | 18:11 |
| theShirbiny | I haven't used anything like this in production, but if I were you I would suggest using something like amazon's elastic filesystem, it has redundancy built in | 18:21 |
| theShirbiny | If you can't do that, the best you can do in that case would be making a HA cluster | 18:22 |
| theShirbiny | That means RAID + ISCSI/NTFS + network teaming/bounding | 18:22 |
| theShirbiny | and something like glusterfs | 18:23 |
| theShirbiny | you can cache some files for a while but you will suffer read/write inconsistency ofc | 18:24 |
| theShirbiny | other option might be amazon gateway storage, in short you upload everything to s3 then cache the most frequently accessed files locally | 18:25 |
| theShirbiny | wait, why can't you just add more storage to the host and resize the vms? | 18:29 |
| elacheche | thx for the propositions theShirbiny.. I won't put down the VM to add some space because it's on prodution the product evoluated faster than my plans to cluster the app (clustering JAVA webapps ca be a nightmare) | 20:19 |
| theShirbiny | elacheche, o.O you don't have to put them down, you can just add more disk to the storage pool then attach them to the vms | 20:26 |
| theShirbiny | What's the virtualization environment? kvm? | 20:26 |
| elacheche | kvm using proxmox | 20:27 |
| theShirbiny | I haven't used proxmox, but that can be done with normal libvirt | 20:27 |
| theShirbiny | try it yourself you can attach/detach block devices while running | 20:28 |
| elacheche | Emm.. In my other libvirt server (testing) I used to shutdown the vm then cat a 10gb file to the disk file to add space to it.. Never knew about that feature.. I'll investigate that and try it (I have a spare "production" vm that I an test with) thx theShirbiny :) | 20:30 |
| theShirbiny | yw :), let me know what you will do | 20:31 |
| elacheche | I'll work on that by monday, now it's weekend :D You work tomorrow, I don't :p | 20:59 |
